[PATCH v2] scsi/bfa: use designated initializers

[Kees Cook <keescook@chromium.org>]

Prepare to mark sensitive kernel structures for randomization by making
sure they're using designated initializers. These were identified during
allyesconfig builds of x86, arm, and arm64, with most initializer fixes
extracted from grsecurity.

This has been updated now that struct bfa_fcs_mod_s was dropped.
